Pintles

[robin_davies]

Please could someone advise on replacing a missing rudder pintle? I’ve taken on a Daemon with rotating stock and have never seen what it had for a pintle. I can source steel rod but can’t see how to retain it in place!
I found an old thread on this topic of pintles that talks about tapping a thread for a nut. I don’t have the skills/tools for that!

What do you recommend, what are my options?

Thanks,

8mm stainless bar

Most of mine are held in place with a washer and some tape. Crap when little hands remove the tatty bits of tape and call it helping

Next best (and second quickest).  Grind a flat sspot, then drill a hole for a ring

Others use balls of epoxy and yes, thread the  end is fairly neat


Generally the pin has no axial requirements.

That stock has had many many alterations to that meachism - for some reason i have memory of making the stoxl fixed and the adjustment being in the gantry?

Thank you! The gantry is now solid - I’m sure you are right about the history of it as there are signs of previous works.

Cool - so no rotating plate inside a slot ?

Here are images of the gantry and stock.

The two blocks on the back of the boat are for the t-foil control. I think the go out to cleats near the deck/rack connection.

The rope connects from these blocks to 2 more blocks that are on pin. The rope thengoes to the tiller and sets the position (via ab 8:1 or 16L1 cascade). Those photos spark a memory of all the ropes being below the tiller. The slider inside just becomes the thing to keep it all in line.


I think there were 3 blocks on the pin, 2 for the control line and the other for a cascade. The key is that the rope pulls the tiller so the pin tries to move forward. A "Lots" to 1 ratio here helps find a setting - although that foil has a wide sweet spot

That foil always tries to pull to negativem so a bungee also acts as a pull in that direciton.

If the blocks are 8mm Allens, they can actually sit on the pin, meaning the system does not put more foil when you steer

That’s helpful, thank you. I’ve made a pin now so I can have a play with the mechanism using your notes.
